' My invention relates to new and useful improvements in a flush `valveand has for its object to provide an Vexceedingly simple and effectivedevice of this description adapted 15 to utilize an air trapped tank ofsuch dimensions as to be placed within the walls of the ordinarybuilding and which will serve to deliver the proper amount of waterunder pressure to the bowl and automatically shut oii the flow of saidwater at a predetermined time.

With these and other ends in view, this in# vention `consists in thedetails of construction and combination of elementshereinaiter setfort-h and then specifically designated by the claims. i

In order that those skilled in the art to which this inventionappertains may understand how to use and make the'sarne, I will 20describe its construction in detail, referring by numerals to theaccompanying drawings forming apart `of this application, in which:

Fig. 1 shows my improved flush valve applied Ato an ordinary bowl andconnected with an air confining tank located within the wall of abuilding.

Fig. 13 is a section of the 'casing -at the line 13-13 of Fig. 3. Incarrying out my invention as herein embodied, 10 represents a relativelysmall air 11 looking 192s.' seriaiNo. 283,578.

trapped tank which is preferably located within the wall of the ordinarybuilding and is supplied with water at any desired point through theservice pipe 11 having the valve 12 therein for regulating theiow ofwater to this tank. i I' From the bottom of the tank the pipe 13 is ledthrough the wall and has threaded thereon the `union nipple 14 carryingthe union nut 15 for screwing upon the threads 16Av formed on the casing17 of the valve whereby a water-tight connection maybe readily madebetween the nipple and the casing as will be readily understood.`

Thebodyof the casing 17 extends downward at an angle and terminates inthedelivery pipe 18 through which water is delivered to the bowl and 19represents an oiiset :for accommodating the stripping dog 20. rilhis dogis secured upon the spindle 21, the latter being journalled in the sidewalls of the oif-set in any well-known manner to prevent leakage whilepermitting the spindle to be turned upon its afxis. y

The spindle 21'extend-s outward at one side of the valve and is curvedas clearly shown in Fig. 2 and has thereon a suitable handle 22 inproper positionfor easy access. i f

` represents theclapper adapted to close upon the `seat 24 and thisclapper isv secured in any suitable manner to the carrying member 25,said member having a threaded stud 26 projecting Ythereiroin through theclapper and on which is run the counter weight 2'? for Y determining thetime relative to the flow of water at which the clapper will be closedvas will behereinater explained.

The member `25 `is preferably tubular shaped having the inclined face 28against which the clapper is secured andso that the clapper may closeinsubstantially a vertical `positionwlfiileithis member extends outwardand downward on the axial lines oi' the cas-V 'ing and projects into thehousing 297 the latter having the slots 30 formed in the outerportionthereoiand through these slots passes the guide pin lcarried bythe casing. This pin .while permitting vthe sliding of the hous- .ingback and forth within the casing pre- CTI ment causes the housing tomove back andi forth with the clapper member while permitting saidmember to be tilted independently of the housing and the particularshape of the lugs 34 and the seats and angular slots prevent thedisengagement of the clapper a member and the housing during the variousmovements thereof. a

Since the housing is held against axial rotation by the pin 31, the lugs34 in engagement with said housing as just described will' also preventthe clapper member from rotaa Ytion upon its axis and thus alwaysmaintain the clapper in proper relative position to its seat. Y

A rib35 carried by the housing serves as a riding surface for theclapper member in its to-and-fro movements relative to the housthuspreventing undue friction.

The clapper member is cut away as indicated at 36 so as to permit thefree iiow of water to the interior of the member when the clapper isopen and also to direct the flow of the water at an upward angle to holdthe valve open as will be presently explained.

37 represents a tongue formed with the member 25 and. this tongueterminates in a heel 38 against which the dog 2O acts to force thismember inward and upward in order that the shoulder 39 carried by thetongue may be brought into engagement with th shoulder 470 formed in thecasing.

From the foregoing description, it will be obvious that when the handle22 is raised, the dog 20 will. force the clapper off its seat, tiltingthe member 25 upon the rib 35 and enthe shoulder 39 with the shoulder 40thereby lifting the inner end of this member and the clapper carriedthereby so that the flow of water from the tank will pass beneath theclapper through the openings 36 and against the upward wall of themember 25, thus holding the clapper open as long as the force of iiow issuflicient to maintain these parts inthis position and sustainthe'counter weight 27 in its elevated position; but when the force ofthe flow of water has been dic the water will close the clapper upon itsseat shutting od any other flow.

The adjustment of the counter weight upon the stud 26 will determine thepoint at which the water will shut off as will be readily understood.

By utilizing an air trapped tank and providing for the-closing of thevalve at a predetermined pressure iiow' of the water, not only thesupply of water in the tank at the time thevalve is open will bedelivered to the bowl, but the additional water which will fiow into thetank after the pressure in the latter falls below the pressure in theservice pipe will also be delivered to the bowl, thus necessitating amuch smaller tanlr than will otherwise be necessary; and as the water isdelivered through the valve under pressure and therefore at high speed,its effectiveness in cleansing the bowl is increased, thus requiring aless quantity of water than where the ordinary gravity tanks are used.

The releasing of the handle 22 and the return of the dog to its normalposition as shown in Fig. 3 prevents interference with the tilting ofthe member v25 and the backward movement of the tongue 37 during theclosing of the clapper upon its seat.

Of courseI do not wish to be limited to the exact details ofconstruction as herein shown, as these may be varied within the limitsof the appended claims without departing from the spirit of myinvention.

Having thus fully described my invention, what I claim as new and usefulis 1.

3. In a valve of the character described having a casing and a seattherein, a housing itted to slide Within said casing, means for holdingsaid housing against rotation, said housing having seats and angularslots formed therein and also having formed thereon a bridge, and atilting member adapted to be tilted upon said bridge as a fulorum,

4. In a valve of jghe character described, a tilting member, said memberhaving an angular face against Which a olapper may be sei cured and alsohaving cut-away portionsin the under side thereof for the direction ofthe flow of Water to the interior of said member7 lugs carried by themember for attaching it to a housing, a tongue also carried by saidmember, a heel carried by the tongue, a dog for coacting With said heelto actuate the housing in one direction, a shoulder formed on the tongueand a shoulder located in the casing for coacting with the first namedshoulder to hold the clapper open during a given speed of the Water flowthrough the casing.
